The Doctor Who 2015 Christmas Special - The Husbands of River Song (Blu-ray)

It's Christmas Day on a remote human colony and the Doctor is hiding from Christmas Carols and Comedy Antlers. But when a crashed spaceship calls upon the Doctor for help, he finds himself recruited into River Song's squad and hurled into a fast and frantic chase across the galaxy. King Hydroflax (Greg Davies) is furious, and his giant Robot bodyguard is out-of- control and coming for them all! Will Nardole (Matt Lucas) survive? And when will River Song work out who the Doctor is? All will be revealed on a starliner full of galactic super-villains and a destination the Doctor has been avoiding for a very long time.
